It is unfortunate that you did not get to spend as much time as you wanted, as there is a real nugget in there!
I like the interesting duality between dice that have slightly better moves (but limited lifetime) against a traditional chess board & pieces.
It is a little hard to follow, with it not being traditionally turn-based (not being sure how many moves the opponent can make) and it felt a bit like a free for all in the end.
Despite that, I think I can see what you were aiming for, and I would like to try it again in the future if you do decide to work on it further!
Good job with what you did achieve though!
